Wont Start


First check that you have 12v(battery voltage) at each coil with key on, center wire at each coil should have 12volts.

Unfortunately the ICM(ignition control module) was put in the computer(PCM) after 1995.
So outside of testing for spark while cranking there is no test I know of for that.

The only other part involved with spark is the CKP sensor, crank position sensor, not Cam position.
It is located near main crank pulley and reads the teeth in a crank mounted wheel(tone ring).
This sensor sends pulses to computer which sets spark base timing, without pulses there is no spark.
The CKP sensor generates its own AC voltage as teeth pass by it, if you hook up a volt meter set to AC volts and crank the engine you should see .5 to 1.5vAC.
If voltage jumps around sensor may be to far away from teeth(tone ring).
The 2 wires for the CKP sensor go directly back to computer, so you would need to removed computer connector to test those wires.

Fords PATS(passive anti-theft) will cut spark if correct key is not used in ignition switch.

There is a longshot issue which I have heard of but have never ran across myself.
The main pulley's woodruff key shearing off, this of course changes the spark timing at CKP.
Just to take that off the table I would set main pulley at TDC 0deg mark then check that #1 piston is indeed at TDC, i.e. remove spark plug and makes sure piston is at the top of it's stroke.
In this case it doesn't matter if it is compression or exhaust stroke, just that TDC mark matches pistons true location, at top dead center.

Thanks for the response. I'll go start checking that stuff and see what I come up with.
 
So I tested everything and it was good. Looked at my trigger wheel and remember when I had it all apart I took it of and put it back on to far. It wasn't lined up with Crank sensor. Tried to start it and nothing. I also had the dash apart to put in a new heater core and had the PATS unplugged. For some reason it reset and its not picking up the key so I have to have it reprogramed. So that's why it wont start now.:annoyed:
 
The "wand" around the key slot is the antenna that "reads" the RFID key when key is inserted and turned on.
The PATS module, on top of glove compartment, is connected to the "wand".
Computer is hooked to PATS Module
The RFID tag numbers are stored in the PATS module some years and computer other years but they can not be reset by anything except the software in a scan device for this purpose, they are stored in nonvolatile memory, so nothing short of melting the parts would erase them, thief's have tried, lol.

So I would check to make sure "wand" wiring is plugged in, connector should be under the steering column.
The "wand" is just a loop of wire that surrounds the key slot

Ok I'll double check that and make sure its all plugged in.
